HYAM JACOB HYAMS, or rrrrsiaune, PENNSYLVANIA, ASSIGNOR OF ONE- HALF HIS RIGHT TO PETER L. BANNEN,

IMPROVEMENT m CARIBUYREVTERS. v

Specification forming part of Letters Patent No. 169.105, dated'October 26, 1875; application filed January 25, 1675.

To all whom it may concern:

Be it known that I, HYAM JACOB HYAMS, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Uarbureter, having for its object the impregnation of atmospheric air with the vapor of gasoline, benzine, or other bydrocarbon fluid. v

The apparatus I have designed, and the manner of its operation, will be readily understood from the followingdescription, taken in connection wit-h the accompanying drawings, wherein Figure 1 represents a side elevation of my improved apparatus for charging atmospheric air with hydrocarbon vapor; Fig; 2, an elevation of that endof the apparatus to which the driving mechanism is applied; Fig. 3, an elevation of the opposite end of the apparatus; Fig. 4, a longitudinal vertical section of the whole machine; Fig. 5, a perspective view of one of the air-forcing drums.

In my apparatus two hollow drums, a b, or cylinders, revolve about a horizontal axis, 0, within another hollow drum or case, A, which case is to be filled with gasoline or other bydrocarbon fluid to a point above its central line or axis; the inner drums being divided into several compartments, 0 e e e, which are similar in every respect, each having an inlet, f, by which air can enter at one end, and an outlet, 9, by which it can escape at the other end, and a passage-way, h, through the center of each, to allow the gasoline to have free ac- .cess to the interior of each revolving chamher. The air enters through the heads of the outer case A by a pipe, B, turned up at each end, and within a hood, E, attached to each of the revolving drums, and so that its open ends may stand above the fluid-line. The parti the same directiomeach will draw the air from the outside and discharge it into the space 1) between them. The approximate faces of the two inner revolving drums are covered by diaphragms F F, of cotton or woolen cloth, fitting tightly around the edges. Surrounding .and inclosing the space Dbetween the dia-. phragms are arranged and fixed, first, a band,

J, of light porous cloth, and next a similar band, K, of heavier or more closely-woven cloth, and over these a covering offine wiregauze, L. A

The apparatus is to'be charged with gasoline or other hydrocarbon fluid until it reaches alevel above the central apertures/1h in the inner drums. The charging is effected by pouring the gasoline into the elevated reservoir 1%, when it will flow down through its vertical stand-pipe 3 into the small chamber ity, its capo screwed tightly down. Theioap n of the short tube is also screwed on, when the valve 10, or cook, between the reservoir and the small outside chamber T, may be so turned or opened as to allow the column of fluid in the stand-pipe and reservoir to rest upon that in the chamber. The lower mouthl ofthe stand-pipe being slightly below the required fluid-line, the gasoline will remain in the reservoir until the fluid in the chamber falls below that point, when that in the reservoir will flow down and again bring it to its proper level, the amount being simply in proportion to the requirements of the apparatus.

After the generator has been charged with gasoline in the manner described, a slow rotary movement is to be imparted to the long central-shaft, and to the revolving drums at I), together with their respective diaphragms F F and porous bandsJ K, which, in this case, is accomplished by placing a pinion, t, on one end of the long central shaft 0, to which the chambered drums are affixed, and gearing it with a large toothed wheel, P, the axis of which is above the fluid-line. These wheels are inclosed in a tight casing, G, and the shaft of the larger wheel extends through the side of shaft is supported on the outside by a suitable frame, W, and on its extreme end is placed acrank, Z, by which it may be turned as a indlass, to wind around it a cord, 0, to one end of which is attached a weight, X, heavy enough to drive the mechanism of the gas-genand asit rises that compartment becomes filledwith air. As the rotation goes on the inlet will become submerged, and at that moment the outlet will rise above the surface of the fluid,which, on entering the compartment,

will force the air out at the discharging end of the drum through the saturated porous cloth diaphragms F F, bands of cloth J K, and wiregauze covering L, becoming thereby thoroughly permeated with molecules of gasoline, in which condition, and thus charged "witliilluminating material, it rises into the upper part of the outer casing A above the fluid-line, andis drawn off from thence for use through a pipe, H. By a further revolution of the drum the said compartment comes into a position to be again filled with air, as already de scribed. That which takes placeinone com partment takes place for all of them in both drums. By the time that the mouth of one compartment in one drum becomes closed by passing m below the fluid the mouth of the compartment in the opposite drum will become uncovered,

andthe air will in a similar way enter it. After a time the compartment in the first drum "will rise above the fluid, and will commence discharging the air it has received; and before this compartment is completely submerged and emptied anothercompartment will commence discharging, andso the operation continues.

The pipe H, by which the impregnatedat mosphere or vapor passes from the generator to the burners, is turned down on the outside of the case, and provided with a cock, U, furnished with along arm, Y extendhl g into the path of the descending weight X, and so arranged as that, when the weight has nearly run down, it will press upon the said arm, and thereby close the cock, thus preventing any escape of vapor in that direction while the apparatus is not in operation. a
